EXTENSION-TABLE.

Specification of Letters Patent.

Application filed April 19, 1911.

Patented Feb. 2a, 191T. Serial No. 622,082.

To all whom it may concern Be it known that T, VIo'roR F. NnUMnNN, a citizen of the United States, and a resident hattan, in the county and State of New York, have invented a new and Improved FixtensiomTable; of which the following is a full, clear, and exact description.

My invention is an extension table of im-' proved type, and embodies a plurality of sections or leaves which, when not in use, can be pushed in out of the way under the table top. An equal number of extensions'or leaves are used at opposite ends of the table sothat the table can be lengthened at one or both ends, as desired. Furthermore, when the length of the table top is increased by means of the extensions provided for thatpurpose, one or more of the sald extensions can be employed, so that the top of the table can be lengthened at either or both ends to a greater or less degree. These and other features will be fully pointed out in the accom panying description and set forth particularly in the claims appended thereto.

Reference is to be had to the accompanying drawings forming a part of thls specification, in which the same characters of reference indicate the same parts in all the views.

Figure 1 is a perspective view of my improved table; with the extensions pushed in under the top; Fig. 2 is a side elevation, showing the top of the table lengthened by the width of a single extension at one end; Fig. 3 is a side elevation, showing the top of the table lengthened at both ends by the combined width of all the extensions; Fig. 4 is a top view of the table frame, with the top of the table taken ofl' Fig. 5 1s a longitudinal vertical section taken through the table on the line 55 of Fig. 4; Fig. 6 is a perspective viewof the guides for the table extensions; Fig. 7 is a side elevation of the sliding supports for the table extensions, the latter being shown in transverse sectlon; Flg. 8 1s a perspective view of one of the hooks for the outermost table extension, and the guide groove therefor; Fig. 9 presentsiseveral details; Fig. 10 presents av perspective view of 'mechanismby means of'which the top of the table can be raised when the table is to be extended; and Fig. 11 is a perspective view of the spring catch which holds the table top lifting mechanism in adjusted position.

0n the drawings, the numeral]. desi ates the top frame of a table having legs or supthe notches 9,

ports at the corners. This frame supports the top 2, which can be raised and lowered in a manner to be subsequently described, and extension boards 3 and 4. These boards are arranged at either end, and slide under the table top when they are not needed. The extension boards 3 and 4 at each end of the table are transversely mounted upon apair of sliding rods 5, which are covered along the top and outer sides thereof by means of an angle-bar 6. This angle-bar 6 has a down-turned inner end 7, which is perforated to receive a guide-rod 8. These guiderods are attached to eitherend of the table frame 1, and are arranged in pairs, as shown on Fig. 4, the extension boards at the right of the table being attached by parts 5, 6 and 'Z, to the inner pair of guide-rods 8, which are secured to the opposite or left end of the frame 1; and the extension boards 3 and 4 at the left of the table are mounted so as to slide upon the outer pair of-guide rods 8, attached at their outer ends to the righthand end of the table-frame. The uncovered side of the sliding rods 5 is beveled, as shown, to fit into a corresponding notch 9 in the sides of the table frame. This will pre vent the sliding rods 5 from jumping out of and will thus prevent the table from getting out of order. The extension boards 3 are rigidly connected to the sliding rods 5 by means of screws 10, but the outer extension boards 4 are movably mounted with respect to these rods 5.

The table top can be raised and lowered so that when the table is only partly extended,

as shown on Fig. 2, some of the extension boards will be housed beneath the top; but when the table is fully extended, as on Fig. 3, the top 2 will be lowered until it is level with the top surfaces of the boards 3 and 4, making a continuous surfac The means for raising the table top 2 is shown on Fig. 10, and comprises a U-shaped plate 11, having out-turned ends 12 with perforations therethrough, to receive bolts or screws which pass into the top 2. This plate 11 fits into a notch or recess in the opposite sides of the frame 1, blocks 13 being employed to reinforce the frame on each side of the recess, and within the borders of the frame, as shown. Beneath the center of the recess and extending acrossthe table frameis an operating rod'l l having laterally-bent ends 15, connected to a handle 16 havin cams 17 on the end adjacent the rod 14:. T ese cams 17 between its ends, the rod 14 is bent outward and back, as shown at 19, forming a pro ection or shoulder which rests against a trans verse spring 20. Beneath this spring 20 is a recess 21, formed in a transverse member 22,

which is attached to the frame 1 at its ends.

This spring will act upon the projection or shoulder 19 to hold the rod 14 and the cam handle 16 in position when the plate 11, with the table top 2, is upor down.

. The outer extension 4 at each end of the table has its opposite ends provided with a pair of hooks 23, attached to the under side thereof. These hooks 23 have in-turned lower ends 24, and move up and down in a slot 25 in the outer end of the angle-bar 6. At the end of these angle-bars, and between the vertical parts thereof and the side of the sliding rods 5, are arranged three plates 26,

27 and 28. These plates are shown on Figs.-

8 and 9. It will be observed that the plate 26, which is the outermost, has a number of studs passing through corresponding openings in all together. The plate 27 has a curved groove 29 therein, this groove curving upward and communicating at its upper end withthe side-of an open notch 30 in the upper edge of the plate 27. A lateral notch 31 is formed in the side of the groove at its 0pposite'end. The plate 26. has a notch 32 therein, correspondingto the lower end of .the' groove 29, the upper endof this notch flaring outward at one side to form a curved edge 33, which correspondsto the curvature of the lower edge of the groove 29 in the plate 27. The plate 26 also has a rabbeted upper left-hand corner 34, the vertical edge of thisrabbeted portion corresponding with the right-hand edge of the notch 30 in the plate 27. The plate 26 is in the same vertical plane as the slot 25 and the hook 23.

Behind the plate 27 is the third plate 28,

which has four transverse cuts made therein.

The body of the plate between these cuts is pushedoutward to form spring catches 34 and 35, the ends of these spring catches being bent over, as shown at 34' and 35 to engage the end 24 of the hook 23. These catches will hold the hook when it is in one end or the other of the groove 29 in the plate 27, so -that the extension board 4 will be firmly retained in either its upper or lower position.

Suppose all the extensions are drawn out as shown on Fig. 3, then, if it be desired to push them back under the table top 2 and the plates 27 and 28, holding them out of the way, the top 2 is raised by means of the handle 16, and the rods 5 are pushed in under the top, as far as they will go. This will close up the table and house the extension boards 3 and 4, as shown on Fig. 1. Suppose, now, it be desired to extend the table by the width of a single board at one or both ends; in such a case the rods 5 will be drawn out as shown on Fig. 2, and the extension board 4 will be swung up 'to the position shown on Fig. 7. The end 24 of the hook 23 will be pulled loose from engagement with the spring catch 35, and travel upthe grooves 29 and 34 in the plates 26 and 27 until it reaches the upper end of these grooves. It will then drop down into the recesses 30 and 34, and be engaged by the upper spring catch 34'. This will hold the end of the hook against displacement, and

hold the extension board 4 in raised position; the inner beveled edge of this board will fit against the end of the table and form a continuation of .the top surface. The same result can be secured with the board 4 at the other end, and either of the boards 4 can be again lowered by pulling up on the outer ends until the end 24 of the hook 23 is disengaged from the catch 34. The board 4 can then be moved so that the end 24 of the catch 23 will then slide down in the grooves 29 and 33 until the board once more rests fiat on the upper surfaces of the sliding rods 5. The rods 5 can then be pushed back under the table top in order to get the extension boards 3 and 4 out of the way.

The extension boards 3 and 4 at either end of the table are connected by means of hinged plates 36 and 37, pivotally connected to an intermediate member 38. This member 38 bears a -spring 39 on its lower side, which engages with a spring 40 embedded in the bottom of the board 4, and having its end protruding into a recess 41 in the bottom of this board. The part 39 and the spring 41, when the board4 is raised, serve to make the board 4 as steady as possible.

By means of the above construction it will be apparent that I can extend my table at both ends, either to the full amount or to a less degree; and I can extend either end of the table to a greater or less extent in this way independent of the other end. Referring to Fig. 10,1 wish it to be understood that I can form the plate 11 so that it will move up and down in the space between the ends of the blocks 13, the blocks 13 serva case the guideway in the U-shaped plate 11 would not be formed in the sides of the tablel.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:

1. An extension table having a top and a plurality of legs for supporting said top ing as guideways for this purpose. In such boards are in projecting position.

2. An extension table having'a top, means for raising and lowering said top, extension boards normally housed beneath said top, sliding means or drawing out said extension boards to extend said table, one of said extension boards having an adjustable connection with the said sliding means, to permit the same to be raised to the level of said top when the said board is drawn out, whereby the table can be partly extended by means of the adjustable extension board, or fully extended by means of all of the extension boards, and means for lowering the table when fully extended, to cause the extension boards to form a continuation of the table top. i

3. An extension table comprising a pair of guide rods and an extension board transversely mounted on said rods, means forming a pair of upward extending grooves in the outer ends of each of said rods, a connection having a projection entering said grooves, said connection being secured to said board adjacent the outer edge of the versely mounted thereon, said guide rods having means at their outer ends forming upward-extending grooves, locking means secured to the rods adjacent said grooves, connections having projections extending into said grooves, and said connections be-' ing secured to, the board adjacent its outer end, and pivotal spring-controlled connections between said guide rods and said board adjacent the inner edge thereof.

5. An extension table comprising a pair of guide rods and an extension board transversely mounted thereon, means forming upward-extending grooves in the outer ends 0 said rods, a plate carried by each of said rods and having a slot therein adjacent said grooves, a connection secured to the board adjacent the outer edge passing through said slot and having a projection entering said grooves, locking means carried by the rod adjacent the grooves toengage the projection, and pivotal spring-controlled connections between the rods and the board adjacent the inner edge of the same.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
